5.0 out of 5 stars Excellent product, September 6, 2001

This review is from: Seiko ED5640 American Heritage Dictionary and Roget's New Thesaurus (Office Product)
I thought this product was so good I'm buying 2 more for other members of my family. I had tried a comparable Franklin Dictionary and compared to this one it did not hold up. The quizes are better and easier to take and I think it's just an all over superior product.

3.0 out of 5 stars a handy tool; good value for the price, June 7, 2002

This review is from: Seiko ED5640 American Heritage Dictionary and Roget's New Thesaurus (Office Product)
This Seiko Dictionary and Thesaurus is a great companion. Compared to a traditional dictionary and a thesaurus, it's less expensive, it's easier to carry, and has a better user interface.

I'm skeptical of the claim that it has 220,000 definitions. It is missing some words that are in my 60,000-word dictionary, such as "defenestrate" and "valetudinarian". In some cases, multiple entries refer to the same definition. (If you look up "volatility", you get the definition for "volatile".) Perhaps it has 220,000 _entries_, but not 220,000 definitions?

When I ordered this product from Amazon.com, it arrived with two sets of Spanish instructions and no English instructions. I contacted Seiko customer service about this three months ago and they promised me a set of English instructions. It never arrived, and now Seiko customer service doesn't even answer my e-mails.

Fortunately, the product is easy to figure out without instructions. :-)

In spite of the questionable number of definitions and the poor customer service, I give it a full 3 stars because it was so inexpensive.

This is a great, inexpensive little product!! It is compact and convenient to use. It is terrific for people who cannot spell, alike myself. I only wish there were more words listed in the dictionary!
